what are the subnet masks defined on 192.168.216.A and 192.168.209.B ?

assuming the answer to my above question is 255.255.255.0, then noone
has a route to this 192.168.0.1 as its in an entirely different
subnet. you can't overlap subnets with different size masks without
creating some serious messes.

there's no route defined to do that, since 192.168.209.B is not in any
network that A has knowlege of. A would need an IP in the B subnet,
and B would need an IP in the A subnet for this to work.
why do you have two seperate LAN subnets? are you running two seperate
LANs ? there have to be some really good reasons before I create
anything this messy.
for instance...
host A with eth0[aaa.bbb.ccc.A] and eth1[192.168.216.A] and eth1[192.168.209.A]
host B with eth0[aaa.bbb.ccc.B] and eth1[192.168.209.B] and eth1[192.168.216.B]
now A can reach B via its eth1 as it now has a route to 192.168.216/24
